Did 18000 miles on my RR mostly back roads, 5000miles without the corbin and the rest with it, and like he said thats the best 200$ i ever spent in my life.I commute on my bike and my heiny comfort is important!! I had a corbin for my F4i and the first thing I got for my RR was a Corbin. As far as I'm concerned, it was the best $200 I ever spent on the bike. My ride height didn't change. After about 200 miles on the corbin, the bike fits like a glove. The stock seat never gave that kind of support. As well, I don't know if you have the ability to compare the saddles side by side, but there is no comparison in quality of workmanship. The stock seat is just cheap foam on plastic, wrapped with vinyl.
Just my opinion but any bike I buy, unless a a GoldWing, will get a corbin installed
